Chug landscapes Date: various Location: Chug valley, Dirang circle, West Kameng district, Arunachal Pradesh, India. Short description: This collection of videos, audio and photo files displays Chug landscapes between 2012 and 2017. The Duhumbi people live in a valley traditionally known as the Chug valley. This valley is located on the southern slopes of the Eastern Himalayan ranges, but not directly on the slopes descending from the great Himalayan range. The watershed between the Tibetan plateau and the southern Himalayan ranges lies to the north and descends till the Mago valley where we find the Brokpa villages of Mago, Thingbu (Thengpoche) and Luguthang (Lungthang, Lugorthang). Between Lungthang and Chug lies the Zela massif, which runs in south-westerly direction from the main Himalayan range till the Bhutan border. The Chug valley has a north to south orientation and is intersected in the middle by the Chug river, locally known simply as Khow Odok ‘big water’, Phrangley Khow ‘Phrangley water’, Khowma Khow ‘water-mother water’, with khowma commonly referring to a big streaming water body, Mangkhow ‘community water’ or Chuk khow ‘Chug water’. The altitude of the valley varies between around 1,650m in the south till 4,848m in the north, with the permanently inhabited part of the valley in the 1,650-2,150m altitudinal range. Figure MAP9999b (courtesy Debby Patterson) shows the location of the Chug valley within western Arunachal Pradesh. The northern border of the Chug valley is formed by the watershed between the tributaries of the Chug river and a tributary of the Mago river, roughly at 27°33'N, and generally located above 4,000m. On the north bank of the latter tributary we find the Brokpa village of Lungthang. This alpine, high-altitude area above the treeline is marked with a few glacial lakes, including the famous Dawa Photsang Motsang lakes. The vegetation is marked by various alpine scrub species, including ɕukpuɕiŋ ‘juniper’ Juniperus recurva and Rhododendron spp. Towering above and around the glacial valleys are four great peaks: from west to east Jomo Using Buthri, Phu Dumba, Phu Phrangley and Phu Tsorgan (Figure 1). If one crosses between Phu Dumba and Phu Phrangley and passes Dawa Photsang Motsang lakes, one arrives at Lungthang village. The glacial valleys, feeding the streams with melting water in spring, rapidly and steeply descend, and as soon as the treeline is reached they are marked by thick forests. Figure 1: The main peaks of the Chug valley. From left to right Jomo Using Butri, Phu Dumba, Phu Phrangley, and Phu Tsorgan The western border of the Chug valley is formed by a ridge running north to south, roughly around 92°11'E. This ridge, with an altitude between 2,500 and 4,500m, forms the traditional border between the Chug valley and the next valley, which falls under the Brokpa village of Nyukmadung. On this ridge are the hills of Phu Kopiri in the south, Phu Goncung Norbu to its north, and the triplet Phu Hrekpa Hrekcung, Phu Takalang and Phu Yangri from northwest to southeast. The eastern border of the Chug valley is formed by a ridge with an altitude between 2,500 and 3,500m, approximately at 92°25'E, directly running due south from Phu Tsorgan (called Atha Namba in Sangthi, cf. §2.4.2 and §2.4.3). Beyond this ridge lies the Sangthi valley, now inhabited by Tshangla speakers. Traditionally, there is no border between these two valleys, as the inhabitants are considered the descendants of two brothers. The names of the streams flowing down from either side of this watershed, one feeding the Sangthi Gongri and the other the Chug Mangkhow, are also homonymous, such as, for example, the Tsangparong stream. From north to south, the rounded hill tops of this ridge are called Phu Nangphu, Phu Laphek, Phu Namsri and Phu Pharchu. In the north, the forests are characterised by coniferous species. In the fir-dominated forest between 2,700 to 3,800m the main tree species are fir Abies densa, sometimes mixed with hemlock and birch Betula alnoides. Below that, and on the northern fringes of the western and eastern ridges between 2,000 to 2,700m, there are a few pockets with mixed coniferous forest dominated by spruce Picea spinulosa, hemlock Tsuga dumosa and larch Larix griffithiana. In the north, and on the eastern ridge, we also find a blue pine-dominated forest between 1,800 to 3,000m with Pinus wallichiana, Quercus spp. and Rhododendron spp. Most of the lower slopes in the north and east of the valley, between 2,000 and 2,900m, are covered by thick cool moist broadleaf forest consisting of mixed deciduous and evergreen species, such as Quercus semecarpifolia, Quercus griffithii, Rhododendron spp., Castanopsis spp., Schima walichii, Daphniphyllum chartaceum, Symplocus spp., Exbucklandia populnea, Acer spp., Persea spp., Alnus nepalensis and their associates. The forests on the western slopes and those closest to the settlements in the valley from 1,800 to 2,600m consist of evergreen oak characterised by dense undergrowth of shrubs, ferns, climbers, bamboos and epiphytes. In this forest, Quercus lamellosa and Quercus lanata dominate alongside Acer campbellii and Castonopsis hystrix. In the south, the traditional border between the Chug valley and Lish village used to be formed by the Gongri river at around 27°23'N and an altitude of around 1,650m. All the land to the north of the Gongri, to the west of the ridge separating Chug valley from Sangthi valley, and to east of the ridge separating the Chug valley from the next valley to the west used to be the Duhumbi’s land. This southern border has for long been contested (cf. Error! Reference source not found.) and there has been a continuous encroachment by the people of Lish northwards into the Chug valley. The border now officially runs at 27°40'N, at least half a kilometre northward into the valley. The dry subtropical river valley at the confluence of the Gongri and Chug rivers at around 1,600 till 1,800m consists of chir pine Pinus roxburghii with undergrowth shrubs and associates. Table 1 presents some prominent landmarks in and near the Chug valley with their approximate GPS coordinates and altitudes for reference. The landmarks circle the Chug valley clockwise, starting in the southwest. TABLE 1.
